clearly describe or indicate something
delineate - outline
When you ‘delineate’ something, you define it in detail so that it is easily understood, or literally mark the lines and boundaries of it. The word is most commonly used in a professional context, particularly with regards to politics and business.
We must delineate the boundaries of this area so there is no confusion over who has the right to use it.
My instructions have been clearly delineated in the email I sent out. Just follow them to the letter and you will have no issues.
The project is a mess at the moment as there has been no delineation of responsibilities. Nobody has a clue what they are supposed to be doing!
